new Jelly Pro doesn't turn on

I removed the battery cover

I connected the USB cable, the phone warms ub (charging?, I measure 3,75V on the battery)

If I press the power-button on the right side (some seconds) nothing happens, the phone is "dead".

I guess the phone should show anything on the screen no matter, whether a sim-card is in or not?

I suppose that the phone has a defect, isn't it?
